Hello,

I want to use active contours (SnakeImage), but i can't find them in Opencv 4.1.0, i know that cvSnakeImage existed in modules in the older versions of Opencv, i can't find an answer to question in this forum or in the internet, and thank you.

it's gone since 3.0 and wont come back (it was numerically unstable, C-api problems, etc.)

why (and what for ?) do you need it ? did you look at AAM implementations outside opencv ?

I need it the resolve a problem of segmentation to detect a shape, i explain my problem here : https://answers.opencv.org/question/2... I can't find an " AAM implementations outside opencv" can you give me a link please, and thank you.

AAM = "Active Appearance Model", "Active Contours", all related to snakes

In my problem i want to detect a shape of a handle of a valve by giving the algorithm the position of the handle, I read know a little bit about AAM, and in my case i think i need only a simple active contour detector. I am working with opencv 4.1.0, do you think if I add legacy module from the old versions of Opencv to the new version it's going to work without problem? And tahnk you

yea, true.

definitely not so.

you'll first have a hard time integrating the removed code, then you'll get into problems using the dead C api, and in the end, it'll just crash or calculate nonsense.

Do you have please any code( c++) i can start with that use a simple Active contour application, i have searched all day, and all the codes i found on github are not working, and thank you.
